Base for LED light bulb



FIG. 1 is a perspective view of a base for LED light bulb showing our new design;

FIG. 2 is a right side elevational view thereof;

FIG. 3 is a top plan view thereof; and,

FIG. 4 is a bottom plan view thereof.

The left side of the illustrated base for LED light bulb is not shown because it is a mirror image of the right side shown in FIG. 2.

Any broken line illustration in the drawing disclosure is not part of the design sought to be patented. 

We claim the ornamental design for a base for LED light bulb, as shown and described.
